Write an Executive Summary

Executives care about the "so what," not the "how."

Structure of a 1-Pager

1. The Problem: We are losing 10% of customers monthly. Costing £1M/year.
2. The Solution: We built a model to predict churn 30 days in advance.
3. The Impact: We can target the top 5% most likely to leave with a £10 voucher.
4. Estimated ROI: Saving 2% of customers = +£200k/year.
5. Cost to run: £10k/year in vouchers.
6. The Ask: We need approval to run an A/B test on 10,000 customers next month.

What NOT to Include

• What algorithm you used (unless asked).
• How you scaled the data.
• What a confusion matrix is.
• Detailed hyperparameter tables.
